Chris, would that be approximate cost to me as well? I have a BQ core to send back. Which tranny would this be anyways? I'm looking for one to handle 4-500 hp. By the way Bob, DO NOT HAVE AAMCO DO IT!!!! I'm currently suing them because they can't build the thing right after numerous tries and will not admit it is not right. They also will try to screw you out of the warranty saying they don't build race cars even though mine is my daily driver and will probably never be put on a track. Your best bet is to have one of the tranny builders on this site do it for you.
